Error handling protocols
All basic Common File System methods and file stream class methods support integrated error handling by answering an instance of CfsError if an error occurs. Error constants are the same on all platforms, and are a subset of the POSIX.1 error constants. To determine if an error has occurred, send isCfsError to the result returned from the operation. Only instances of CfsError answer true to this message. All other objects answer false.
